  2. republican jewelry wholesale The concept of platinum and platinum

    At present, there are two major consumption misunderstandings for platinum jewelry. The first is to mistake platinum by mistake. The two are confused. The second is that you do not know how to use the "PT" logo to identify platinum accessories. In fact, platinum and platinum are completely two -cordon.

    1. The concept of platinum

    The name of platinum is derived from the Spanish "Platina Del Pinto", which is translated as a white metal similar to silver in the Pinto River. The metal made of platinum elements minerals, including gold, gold, platinum, and gold. Generally, platinum is melted from platinum ore such as natural platinum and rough platinum ore. It is a rare valuable metal composed of platinum or all composed of platinum, which is equivalent to valuable metals as gold and silver.

    2, the concept of platinum

    The whole name should be "white K gold". It is a platinum -free white alloy melted from gold and other white metals. Among them, the percentage of gold is up to 75%. Because this alloy is white, it is called platinum.
    The meaning of platinum jewelry label

    "PT" is the unique chemical element symbol of platinum elements, and it is also the unique component logo of platinum jewelry. Platinum cannot be on the proprietary sign of "PT". In accordance with the regulations of the State Technical Supervision Bureau, all platinum jewelry produced in China should marked the "PT" proprietary sign.

    . Generally, the platinum content of platinum jewelry is shown in the prime content of platinum. At the same time, platinum content is also one of the basis for platinum jewelry pricing. Common platinum content marks are the following:

    Footing platinum: Platinum content is not less than 990, and "foot platinum" or "PT990" mark 99%.

    950 Platinum: The platinum content is not less than 950, and the "platinum 950" or "PT950" mark indicates that the platinum in the jewelry is 95%.

    900 Platinum: The platinum content is not less than 900, and the "platinum 900" or "PT900" mark, indicating that the platinum content in the jewelry is 90%.

    It on foreign platinum jewelry, the words "PT", "Plat" or "PM" are generally engraved. There are such bids a platinum jewelry.

    The platinum jewelry produced in my country, in addition to the business name, also has the words "platinum", "true platinum", "orthopedic platinum" and other words. If the seal on the jewelry is "S" or "Silver", it is a silver jewelry. If the accessories are marked with the words "Platinum" or "K platinum", it indicates that it is not pure platinum jewelry or a platinum jewelry at all.
    -k gold is a alloy dominated by gold.
    -Add a certain percentage of other metals (such as copper, silver, zinc, nickel, etc.) to gold in gold. This alloy is called K gold in the jewelry industry.
    -k gold is represented by K value, and it is converted with pure gold as 24K:
    -24k = 100 % gold (theoretical value)
    18k/24k = 75 % that is 75 % n18k/24K = 75 % R n14K/24K = 58.5 % 12K/24K = 50 %
    K gold color depends on the types and quantities of other metals contained in it. Natural gold is a typical golden yellow, but in order to increase its hardness, durability and color changes, gold can be mixed with other metals into alloys. Theoretically 24K is pure gold, 18K contains 75 % pure gold, and the word print is AU750. The greater the proportion of jewelry containing pure gold, the higher its value.
    mi mixing with other metals and other metals will form different colors of alloys. Color changes can be from light yellow to rose red, or white. Add copper and silver in gold to yellow K gold, add a large proportion of silver to white gold, and add copper to synthesize red or pink.
    k gold jewelry maintenance
    This to avoid contact with chemicals such as bleach water, detergent, etc., and you also need to avoid wearing K gold ornaments when dealing with housework.
    The diluted soap liquid is cleaned, and the water is dry with soft cloth. It can be used to remove the surface fingerprints and stains with non -sharpening cloth, such as silver cloth or glasses cloth.
    Is avoid placing K gold jewelry with other jewelry, especially diamonds. Because of its hardness, it can be scratched by rubbing each other. Therefore, it should be stored independently with a cloth box. On November 1, 2009, the latest revised national standard "Regulations and Names of the Pure of Jewelry Metals" (hereinafter referred to as the "New Standard") was officially implemented. In order to conform to the development of the Chinese platinum market, the new standard has been revised two main points for platinum jewelry: adding the purity range of platinum jewelry, and clearly stipulated the purity of platinum accessories; Chinese must be marked.
    The new standards further regulate the platinum jewelry market. The revision increased the purity range of platinum jewelry, which standardized the method of purity marks. Like thousands of gold, 999 pure platinum can be called thousands of platinum, thousands of platinum, or thousands of platinum. The purity identification of platinum jewelry must be expressed as platinum (platinum, platinum) 950 or platinum PT 950, which is clear that only platinum can be called platinum, thereby avoiding confusion of the concept of "platinum" in the retail market, because not all white is not all white. Precious metals can be called "platinum", and "platinum" is a special referring to platinum, so the name of the so -called "K platinum" will exist.
    The second, the new standard further protects consumer rights. Due to regional differences, consumers in various places have different awareness of jewelry, and some consumers do not know what PT, PD, and AU represent them. In response to this situation, the new standard stipulates that the naming of precious metal jewelry must include purity, materials, gem names, and varieties. At the same time, it is clear that enterprises can be expressed in Chinese or Chinese and English in the label, but they must not be represented by English letters. For example: Platinum 950, Platinum (PT) 950, Platinum 950, Platinum (PT) 950, etc. are all possible. When buying jewelry, as long as the product label contains the specified information, it can distinguish the jewelry category and ensure that the real platinum jewelry is purchased.
